Abstract

PURPOSE: To prevent rusting and tightening of a rotor by interposing shut-off valves with small hole on the way of each exhaust pipe.
CONSTITUTION: Shut-off valves 11W13 equipped with valve plates 11c with small hole 11d are installed on the way of exhaust pipes 8W10 of blowers 1W3 in plural parallel. When driving condition is transferred from the blowers 1, 2 to the blowers 2, 3, part of high temperature air in a collective pipe 14 passes through the small hole 11d via the exhaust pipe 8 and gets into the blower 1 in dormancy, and at the same time as the high temperature air which remains in the exhaust pipe 8 and in the blower 1 is held as it remains in high temperature, a rotor in the dormant blower 1 is reversely turned at a very slow speed. Thus, since liquefying phenomena due to cooling of the high temperature air in the exhaust pipe 8 and in the blower 1 is not generated, rusting and tightening of the rotor can be prevented.
